Abstract

The 255 species of scarabaeoid beetles occurring in the Great Plains state of Nebraska are comprehensively reviewed. An overview of the land forms, climate, and vegetation of the state is presented. The classification of the superfamily Scarabaeoidea is reviewed, and keys to the families occurring in Nebraska are presented. Included within each family treatment are an introduction, keys to all taxa, descriptions, distributions, diagnosis, notes on biology, illustrations, and maps for all species. Literature cited, a glossary of terms, and a species checklist conclude the volume.

The Nebraska fauna comprises 14% of the Nearctic fauna. The Nebraska species are found in 7 families: Passalidae (1), Geotrupidae (13), Trogidae (24), Lucanidae (6), Ochodaeidae (6), Hybosoridae (2), and Scarabaeidae (203) in the following subfamilies: Aphodiinae (75), Scarabaeinae (22), Melolonthinae (64), Rutelinae (12), Dynastinae (13), and Cetoniinae (18). Since the last synopsis of Nebraska scarabs 16 years ago, 47 additional species have been discovered in the state, an increase of 23%.
